Before printing the first part with LW-PLA, it is recommended to run a test print. Make sure the wall thickness is between 0.55 – 0.65 mm and bridging works.

After printing, measure the wall thickness with a caliper. Wall thickness depends on both “nozzle temperature” and “extrusion multiplier”.
– If under-extruded (too thin): increase “nozzle temperature” first.
– If over-extruded (too thick): decrease the extrusion multiplier (flow rate).
Also monitor bridging performance closely, because too high temperature can worsen bridging.
– If bridging fails, lower the temperature and may increase the extrusion multiplier (flow rate) slightly to compensate, only if necessary or you can play with “Bridge Flow Ratio”.

Once you find the correct settings for your own LW-PLA, save them as your custom filament profile!
